GRAIN-BINDER.

SIECIFICATION forming part of Letters Patent No. 286,899, dated October 16, 1883. Application filed January 23, 1ss2. (Model-l To all whom it .ma-y concern.- Be it known that I, JosErH P. BULLOCK, of Milwaukee, in the county of Milwaukee, and in the State of Wisconsin, have invented certain new and useful Improvements in Grain- Binders; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to grain-binders, and 'will be fully described 'hereinafter.

In the drawings, Figure 1 is an end view of a grain-binder embodying my invention, and showing the position of the parts when the binding mechanism is at rest. Fig. 2 is alike I 5 view, showing the position of the parts when the binding mechanism is in operation andthe cam-wheel has made a half-revolution; and Fig. 3 is a section taken just inside of the standard when the binding mechanism is at what is called half-travel. Fig. 4 is a plan view of parts shown in Fig. 1.

A is the cast-iron standard common to binders, from which project outwardly studs a b, that form bearings for cog-wheels 1 and 2, and 2 5 in which are also the bearings for shafts c d. An arm, a, that projects from the rear of the standard A, affords a bearing for the shaft E, that operates packers H.

G is a rock-shaft that turns in hearings in the arm or bracket G, and in a slanting beam, 9, and this rock-shaft G forms an axis for the links h 71, that are loosely sleeved on the'shaft and hold the lower ends of the. packers H. Between the hubs of the links it h, with suitable sleeves interposed, I key the compressor G on the shaft G, so that when therock-shaft G turns it will carry the compressor with it. The crank-arm g of shaft G is connectedwith the short arm I of a pivoted trip-lever, I, by a 4 link or strap, 9, that is screwed into a wristpin, t, that turns in the end of said arm I, and is slotted to slide upona wrist-pin, in crankarm 9. Just above the pin the lower end of a sectional spring-rod, M, is swiveled to the 4.5 crank-army, and the other end of this red is swiveledto one arm, q, of a T-shaped lever, N, the long arm q of which is pivoted to the inside of the standard A, and the arm q of this T-shaped lever carries a roller, a, that nut on the end of rod f, to permit the trip travels in a cam-groove in main binder-wheel 5o 3. The main binder-wheel 3 is connected by red L with the crankarmd of ashaft, d, upon which the trip-lever I is loosely sleeved, and which shaft (1 extends through the machine, carrying and operating the needle. The crankarin d is connected with the pivoted trip-1ever I by rod f, that passes through the long arm of the trip-lever. A spring, f, is interposed between the top of the lever I and the 6o lever I to be rocked independently of the crank-arm d of the binder-arm shaft.

E is the continuously-operating driving shaft, and this shaft has cranked to it the packers II II, by which the grain is packed against the compressor. The driving-shaft E has a piniomK, upon its end, just outside of its bearing in standard A, andupon this wheel K a pawl, k, is pivoted, a spring,- e, serving to hold it in position for, its nose 1? to engage with the trip end i of the lever I. VVhenthe trip end 7: of the lever I is in contact withthe nose 1? of the pawl k, the rollers E of a casting, E, fixed on shaft E, will just clear the heel k as the shaft revolves, and consequently the pinion K, which fits loosely on the shaft E, will be unaffected by-the revolution of said shaft as it continuously operates the packers, until enough grain has been packed against the compressor to depress it, as shown in dotted lines, Fig. 3, when it will partially revolve its shaft G, and cause crank-arm 9, through the link or strap 9, to draw upon short arm I of trip-lever I and raise its long arm, so as to disengage the end 12 from contact with nose 6 of pawl 70, and permit spring 0 to throw the heel is out into position to be struck by one of the rollers of casting E, so that as it revolves with the driving-shaft it will revolve the pinion K, which latter, through gears 1 and 2, will revolve the main binder-wheel 3, that has up to this time been stationary. The cam-groove in the main binder-wheel 3 has about the same outlines as that in the main binder-wheel of the wellknown Appleby machines, except that it has an additional curve or depression, a, in which the roller 01. rests when the t ing mechanism is at rest, and just beyond his curved de- I, so that when the crank arm is carried into pression is a raised portion, n which, as it 1 passes under the roller n, lifts it and causes lever N to draw upon rod M and lift the crankarm 9, so as to revolve its shaft and cause the compressor to advance upon the gavel, while the main binder-wheel revolves shaft 0 to tie the knot in the cord that the needle has carried around the gavel, for in its revolution the wheel, acting through rod L, has drawn the crank-arm d from the position shown in Fig. 1 to that shown in Fig. 2, which revolved the shaft (2 just far enough to carry the eye of the needle into the tyer.

That the trip-lever I may be held out of the way of the pawl 70 while a knot is being tied, I provide a stop, 8, 011 the butt of the crankarm d, and another, 8, on the hub of the lever the position shown in Fig. 2 it will draw the trip-lever I over with it.

I make the spring-rod M in two sections, m and m. Over section m, I pass a plate, 0, and then a heavy spring, 0. I then pass'another plate, 1), onto it, and on that I place a spring, 0", very much more flexible than 0, and on top of this another plate, p, and inter posing sleeve 19 between plates 1) and p. I pass rods p through them all and through a plate, m that is headed on rod or section m, and tighten the whole by heads and nuts. The plate 1) is headed on rod or section m, and the sleeve p slid loosely through it. The operation of this rod M is very simple. Itis the medium through which the crank-arm g is supported to hold the compressor up in position to receive the grain, and its spring 0 is just strong enough to support the arm g until a bundle of grain of the proper-size has been packed upon it, while the spring 0 is strong enough to resist the tension required to com press the gavel, and yields only when a bundle of such bulk has been accumulated as would strain, the machine but for such yielding.

R is the eordboX of my improved binder, which I secure to the standard A, so as to be out of the way of the machinery, as well as below it, and from this box I carry the cord ,Or twine up'and pass it through a perforation, R, in the arm (1, and thence through the eye R to the needle. XVhen the arm (1 travels forward to carry the eye of the needle to the tyer, it will draw enough of the cord out of the box to leave a loose string for the next gavel to come down on.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, in a grain-binder, of the clutching mechanism, a pivoted trip -lever, and

"the compressor, with intermediate mechanism between the compressor and the trip-lever, whereby the trip-leverand the compressor are permitted to move independently of each other during the binding operation, but when at rest be in such a position that the accumulated grain will cause the compressor-shaft to throw the trip-lever off of the clutching mechanism, substantially as set forth.

2. The trip-lever, in combination with the compressor-shaft and its crank-arm, and a slotted connecting-strap, as set forth.

8. The combination of the main binder wheel, having the curve or depression in its camgroove, of the compressor-shaft, the spring connecting-rod, and the pivoted lever having a roller taking into the cam-groove, substantially as and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 10th day of January, 1882.

JOS. P. BULLOCK.
